    All the kudos and congratulations are well deserved. I only hope I can pay it forward like you did some day. 🍻

    Pool green for over a year.

    At the very least you probably need to replace the spider gasket. Otherwise, lookin’ pretty good!

    FAS DPD really necessary?

    At least now they’re being honest about their business! 😝

    FAS DPD really necessary?

    You got a lot of answers about pool store testing and test strips, but I’m not seeing any answers to the title of your post. Is the FAS-DPD really necessary? I would say yes. Free Chlorine (FC as we abbreviate it) is the most important parameter of a “balanced” pool. If you use test strips or...

    Muriatic Acid Use

    I can attest to this. I slacked this year and got lazy. Now I have bleached liner around my main drain which I thought was worthless for water circulation 😕

    Muriatic Acid Use

    A clarification, yes, don’t mix muriatic acid and chlorine together. I’ll add acid first, then chlorine an hour later with the pump running throughout both additions. I think some here say 30 minutes minimum, but I’m not usually in a hurry to add chlorine. There is probably something documented...

    Muriatic Acid Use

    Do you have a Home Depot anywhere near? In MN I get 32 baume muriatic acid from HD. I don’t trust Kleanstrip, I researched it once and decided it wasn’t what I wanted, but I don’t remember why. I think some here have said it’s ok, but I’d look around a bit more, a local hardware store may have...

    I forgot you’re fighting bromide. Continued good luck!

    Pool green for over a year.

    Probably need to get all the “gunk” off the bottom, raise CYA to 30, then SLAM. All that chlorine with 0 CYA and a lot of organics means a lot of wasted chlorine. I’m assuming there is still 0 CYA?

    Can I add any sort of "protective layer" on top of my pool's pebble finish?

    Just to be clear, there is no such thing as “old” water. Your current water could have issues that require draining, but you won’t know that until you test it yourself. Get a good test kit (as suggested above), do some reading (also as suggested above) and come back with the results of your...

    Reading the recommendations on TFP makes me concerned pool care is too difficult.

    I’ve seen enough of your posts to know that you know your stuff 🙂 it’s easy enough after a hard day of work to mix something up on a forum doing your best to help others. Much ❤️

    Sorry, but I felt compelled to say something. The tests can be confusing to people new to testing, so I wanted to make sure. 🙂

    Reading the recommendations on TFP makes me concerned pool care is too difficult.

    To do it the way you’re suggesting, you’d have to dump back into the bottle on every fill. If you fill to 100, see dot, 90, see dot, …, 40, see dot, 30 don’t see dot, call it 40 you can do the test without having to dump back in the bottle. That said, you can repeat the test a few times by...

    Pool Nube ( Phosphates )

    Take a step back, take a breath, and notice how everyone trusts your test results over the pool store’s. Nice job, you’re well on your way to a crystal clear, trouble free pool!

    Reading the recommendations on TFP makes me concerned pool care is too difficult.

    Come back here and ask any questions you have about testing. The forum is filled with these, we’ll help you! About the return, put your hand in front of it, if water is gushing out, that is a return. Returns in your pool usually are only off when you aren’t running your main pump.

    Struggling With High TA

    Just to be clear, according to mchamp’s sig, mchamp has a vinyl pool. CSI is still relevant for the SWCG, but not for vinyl liner pools themselves.

    No CYA reading or chlorine

    When did you fill your pool? You said recently, but how recently? It’s hard to believe you’d have ammonia in a newly filled pool unless something was added that had ammonia.

    CYA testing question..

    I've always followed the instructions that are in my k2006 which aligns with the first link you provided. I don't know that second link as well, so would like to see other comments. In the meantime, I'd trust the first link.

    Gritty Deposits on the Bottom of my AGP

    Do you have a sand filter? I get what sounds like you’re getting and for me it’s definitely sand. I can dive down and touch it with my fingers and pick it up. I notice more after I backwash. I don’t get much so I’m not super worried, but it annoys my clean pool OCD 😀

    Instructions for Taylor R-0015 acid demand test ??

    @Riddler0520 I have high TA fill water, so unless I get lots of rain (not this year!), I constantly battle rising pH. Not as bad as you though. My TA (see my pool logs by clicking on my name) typically sits at 100-110. I drop my pH to about 7.4 and within a few days it rises to 7.8 where it sits...

    Instructions for Taylor R-0015 acid demand test ??

    As @JamesW said: If your pH is rising fast, I’d guess you have high TA. What is your TA, as tested with your Taylor test kit?

    CYA testing question..

    70, always use the last value you could see clearly in increments of ten, as you’ve done. The test is logarithmic, so half way is not 65 as you might think it is.

    Instructions for Taylor R-0015 acid demand test ??

    Well, if your water sample is representative of the water population of your pool, the acid demand test is about as good as you can get. When I say my pool volume isn’t dialed in to PoolMath, let’s be clear. My volume fluctuates, especially this year with how little rain we’ve received. And I...

    Help with lowering PH

    Yes, that’s a good call out as well, I usually use my brush to swirl around and brush the area where I dosed the acid, usually in 1 quart increments.

    Help with lowering PH

    Muriatic acid is something that requires care to use properly, but you’ll find that most people here use it regularly. Maybe others can share their methods of using it to help you find a way so that you can become comfortable using it. And storing it I might add. Some forum searches on using and...

    Instructions for Taylor R-0015 acid demand test ??

    I know the question is specifically about running the Taylor acid demand test, but at the risk of digression, I’ll share my experience with it. I used to use the acid demand test to determine my acid additions before I used PoolMath. It was very precise and I would never scare anyone away from...

    Help with lowering PH

    Adding muriatic acid is definitely my least favorite part of pool maintenance … by far! But it’s what we use, so best to get on with it. Distribute from the gallon jug, don’t measure it, eye ball it. Hold your breath if looking into the bottle to see how much you’ve used, but not too close...
